(Joint work with Philipp Reiter.) Aiming at optimizing the shape of closed embedded curves within prescribed isotopy classes, we use a gradient-based approach to approximate stationary points of the Möbius energy. The gradients are computed with respect to certain fractional-order Sobolev scalar products that are adapted to the Möbius energy. I...

We review representation results of the random solutions by so-called 'generalized polynomial chaos' (gpc) expansions in countably many variables. We present recent mathematical results on regularity of such solutions as well as computational approaches for the adaptive numerical Galerkin and Collocation approximations of the infinite dimensiona...

Joint with R. Hiptmair, Konstantin Grella, Eividn Fonn of SAM, ETH.We report on an ongoing project on Sparse Tensor Finite Element Discretizations for High Dimensional Linear Transport Problems.After reviewing several well-posed variational formulations and the regularity of weak solutions of these problems, we discuss their stable discretizatio...

Each of these three posters contains a piece of digital art depicting an aspect of life during the COVID-19 pandemic. The first poster, titled "BORED IN EVERY SQUARE", shows a digital drawing of a laptop computer with a Zoom meeting grid on the screen. Text below the image reads: "The coronavirus forces school to be taught online. I have never s...
